A gas-insulated switchgear in which a busbar switchgear having one side is housed in a busbar switchgear tank placed in the upper or lower part of the main body tank in which an insulating gas is sealed, and a busbar is placed outside the busbar switchgear tank In the first embodiment, the busbar opening / closing device is arranged in such a manner that the axis of the movable shaft that moves linearly is oriented horizontally in the front-rear direction of the busbar opening / closing device tank, and each phase that is configured in multiple phases is arranged in the width direction of the busbar switching device tank. 1 busbar switchgear and a second busbar switchgear arranged in the same manner as the first busbar switchgear above or below the first busbar switchgear. Insulating spacer for connecting the vessels of terminals, it is obtained by enabling through installed at bus switchgear tank to the outside of the three busbar switchgear tank.
Further, in the same configuration as described above, there are two insulating spacers for connecting the bus and the terminal of the bus opening / closing device on the back side of the bus opening / closing device tank, and one on the upper surface side or the lower surface side. Is provided.
Also, a bus opening / closing device tank and a bus similar to the above-described bus opening / closing device tank and bus are arranged above or below an equipment room in which a transformer for power trading is accommodated.

この発明のガス絶縁スイッチギヤによれば、本体タンクの上方又は下方に配置された母線開閉機器タンクに収容される母線開閉機器を、軸線を母線開閉機器タンクの前後方向に水平に向けて配置した第１の母線開閉機器と、第１の母線開閉機器の上方又は下方に第１の母線開閉機器と同様に配置した第２の母線開閉機器とで構成し、母線と母線開閉機器の端子とを接続する絶縁スペーサを、母線開閉機器タンクの外部の３箇所に母線開閉機器タンクを貫通して設けたので、列盤されるガス絶縁スイッチギヤの盤間の母線経路に自由度が増し、列盤構成の縮小化を図ったガス絶縁スイッチギヤを得ることができる。
また、本体タンクに替えて、電力取引用の変成器が収容された機器室とし、機器室の上方又は下方に配置された母線開閉機器タンクを、上記と同様に構成したので、取引用変成器を有する回路構成の場合の列盤配置において、母線接続が容易になり、列盤構成の縮小化を図ることができる。 According to the gas-insulated switchgear of the present invention, the busbar switchgear accommodated in the busbar switchgear tank disposed above or below the main body tank is disposed with its axis line oriented horizontally in the front-rear direction of the busbar switchgear tank. The first bus opening / closing device and the second bus opening / closing device arranged in the same manner as the first bus opening / closing device above or below the first bus opening / closing device, and the bus and the terminal of the bus opening / closing device Insulating spacers to be connected are provided through the bus opening / closing device tanks at three locations outside the bus opening / closing device tanks, so the degree of freedom increases in the bus path between the panels of the gas insulated switchgears that are lined up. A gas-insulated switchgear with a reduced configuration can be obtained.
In addition, instead of the main body tank, it is an equipment room containing a transformer for power trading, and the bus opening / closing equipment tank disposed above or below the equipment room is configured in the same manner as described above. In the circuit board arrangement in the case of a circuit configuration having, the busbar connection becomes easy, and the circuit board configuration can be reduced.
